Which Node.js Version Should a Discord Bot Use?
Understand Node.js version compatibility for Discord.js bots and hosted Node.js applications.
Choosing a Node.js version should be based on the project and dependency requirements. Selecting the newest or oldest version without checking compatibility can create avoidable startup errors.
Check the project requirements first
Review package.json, project documentation and the version requirements of important packages. Projects can define an engines field to document compatible Node.js versions.
"engines": {
"node": ">=20"
}Why old runtimes cause errors
Modern packages can use JavaScript syntax or runtime APIs that older Node.js versions do not understand.
Why changing versions can also break projects
Some older dependencies or native modules may not support every newer runtime immediately. Test upgrades instead of changing production runtime versions without a reason.
Update dependencies carefully
Changing the runtime and every dependency at the same time makes troubleshooting harder. Prefer controlled changes with backups or version control.
Frequently Asked Questions
Should I always use the newest Node.js version?
Use a version supported by the project and its dependencies rather than choosing based only on version number.
Can Node.js version cause Cannot find module?
Usually that specific error relates to module resolution or missing packages, though runtime compatibility can cause other installation and startup failures.
